23    
24            * src/Csparse.c (Csparse_Csparse_crossprod, Csparse_Csparse_prod):

50    
51            * R/Matrix.R (Matrix): no longer use coercions to specific classes
52                    (since we are discouraging them in user code).

95    
96            * R/sparseMatrix.R, et_al (isSymmetric): add '...' to formals, in
97            order to match the generic (and evade .local(..)).
98    
99            * R/dsCMatrix.R: dgC -> dsC: use C code!

160            coercion to "nMatrix" and "pMatrix"
161
